Randomized Controlled Trial Comparative Study Clinical Trial[The use of propofol in carotid surgery].
To compare two anesthetic techniques in carotid surgery. The first technique was propofol in continuous perfusion throughout the procedure (group A) and the other used etomidate for anesthetic induction and isoflurane for maintenance (group B). ⋯ The use of propofol for induction and maintenance during carotid surgery was as safe as conventional anesthetic technique with etomidate and isoflurane.

Randomized Controlled Trial Clinical Trial[The effects of carbonation on 2% mepivacaine in epidural anesthesia].
To evaluate the clinical effects of 2% carbonated mepivacaine in arthroscopic surgery of the knee. ⋯ Alkalinization of 2% mepivacaine delivered epidurally improves the quality of blockade, decreasing time until start of surgery. However, the slight clinical significance of these results does not appear to justify general application.

Randomized Controlled Trial Comparative Study Clinical Trial[Changes in the concentrations of catecholamines and cortisol in balanced anesthesia and total intravenous anesthesia].
To compare hormone response to stress caused by surgery performed under balanced general anesthesia and total intravenous anesthesia. ⋯ Hormone levels are significantly higher during intravenous anesthesia than during balanced anesthesia, and the difference is evident from the earliest measurement performed.

Randomized Controlled Trial Clinical Trial[Air-convection heater for abdominal surgery. Study of the relation between surgical time and the efficacy of body temperature maintenance].
1) To quantify the efficacy of forced air warming for maintaining body temperature during general anesthesia of adults, and 2) to study the relation between the duration of surgery and the level of thermal protection provided by the device used. ⋯ The Bair Hugger heater is effective during abdominal operations lasting two or more hours. The device not only prevented hypothermia from deepening during surgery, but also reversed hypothermia in spite of being used after anesthetic induction and in spite of the loss of heat produced by secondary vasodilation.

Randomized Controlled Trial Comparative Study Clinical Trial[Efficacy of ondansetron in the prevention of nausea and vomiting after laparoscopic cholecystectomy].
To assess the efficacy of 4 mg of intravenous ondansetron versus placebo for the prevention of postoperative nausea and vomiting (PONV) in cholecystectomy, a type of surgery that is highly emetic. A random, double blind, placebo controlled study of 40 women over 18 years of age who were scheduled for non urgent laparoscopic cholecystectomy under general anesthesia. The patients were assigned to two groups to receive ondansetron (n = 23) or placebo (n = 17). ⋯ There were no significant differences between the two groups with respect to biological characteristics or other factors that might influence the presentation or severity of PONV. The percentage of PONV-free patients was significantly higher in the ondansetron group than in the control group (73.91 and 11.76%, respectively; p < 0.001). Intravenous administration of 4 mg ondansetron is significantly superior to placebo for PONV prophylaxis after laparoscopic cholecystectomy.
